ROTARY HAND-STAMP.

SPECIFICATION forming part of Letters Patent No. 391,228, dated October 16, 1888.

Application filed July 5, 1887.

To all whom it may concern.-

Be it known that I, HENRY A. BURBANK, a citizen of the United States, residing at \Vestfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Rotating HandStamps, of which the following is a specification.

This invention relates to rotating handstainps, the object being to provide a stamp of this class of improved construction which is adapted to be used in connection with a suitable handle or to be applied to the end of a pencil for desk use, the pencil serving for the handle, an inking-pad being located in proximity to the type-wheel,whereby the stamp is self-inking; and the invention consists in the peculiar construction and arrangement of the stamp, all as hereinafter fully described, and pointed out in the claim.

In the drawings, forming part of this specification, Figure 1 is a perspective view of a hand-stamp embodying my improvements, a portion of the side of the type-wheel case being shown broken away, and in connection with this figure is shown the end of the finger of the operator applied in operative position to a spring-stop attached to the inner side of the type-wheel case. Fig. 2 is an elevation of the inner side of the type-wheel. Fig. 3 is an end view of the type-wheel case, which is shown partly in section, this figure disclosing in plan view the inking-pad and that portion of the inking-pad case in which it is located. Fig. 4 is an elevation of the periphery of the type wheel. Fig. 5 is an elevation of the outer side of the type-wheel. Fig. 6 is a perspective view of the pivot-bolt of the typewheel. Fig. 7 is a perspective view of a screw by which the pivot-bolt is secured to the typewheel case.

In the drawings, 2 is the type-wheel case, of cylindrical form, constructed, preferably, of sheet metal and having one side open to provide for inserting therein the typewheel 3. Said case 2 has secured to its inner side by one end a stop-spring, 13, having a headed pin, as shown, connected to its free end,which projects through the periphery of the typewheel case in convenient position to permit the operator to place one finger on the head of said pin when he holds the stamp by the han Serial No. 243,325. (No model.)

dle 6. In the side of the type-wheel case is formed an oblong opening to receive the end of the type-wheel pivot-bolt 9, as shown in Fig. 1, a screw, 10, being adapted to be screwed into the said oblong-shaped end of the pivotbolt, 9, whereby the latter is secured to the said case and is prevented from turning when the type-wheel is rotated thereon, as below described.

The type-wheel case 2 is rigidlyfixed by a portion of its border to the open end of the inking-pad case 5, the portion of the border of the type-wheel case which is covered by the inking-pad case being cut away, so that when the inking-pad 4, (see Fig. 3,) of felt or other similar soft absorbent material, is placed in the inkingpad case it presents an inked surface, with which the letters on the typewheel are brought in' contact when said wheel is rotated, whereby the letters are properly inked. The position, substantially, of said inking-pad 4 in the inking-pad case 5 .is indicated by a curved dotted line on the side of said case in Fig. 1, and the exposed side of the inking-pad is shown in Fig. 3. A portion of the periphery and one side of said case has an opening formed therein, whereby the letters on the type'wheel are exposed, as shown in Fig. 1.

The type-wheel 3 consists of a flat metallic band, 02, of suitable sheetmctal, having rigidly secured to one edge thereof the disk (4, which projects beyond the periphery ofsaid band 12. Nhen said typewheel is placed in the typewheel-case 2 in the position shown in Fig. 1, the said disk a constitutes one side of the typewheel case, and its periphery c is milled or knurled, as shown in Fig. 1, so that when the stamp is moved over the surface of paper, or anything upon which it is desired to print the letters of the stamp, the type-wheel will be caused to rotate by the frictional contact of said milled periphery with the paper. Said type-wheel has fixed therein a stop-pin, 14, which is adapted to engage with the end of the aforesaid stop-spring 13 when the free end of the latter is forced inward toward said wheel by the operator, thereby stopping the typewheel at a certain point in its revolution, for the purpose below described. The said disk a, as shown in Fig. 5, has also a stop-mark, e, thereon near its periphery,whereby the operator may see that the revolution of the typewheel should be stopped at a certain point after the wheel has rotated sufficiently to print the matter on the wheel. The said stop-mark e is only another means, in addition to the stop 13 and pin 14, for aiding the operator in arresting the rotation of the type-wheel at will; but neither of these means is essential in the operation of the stamp, for a person who is aceustomed to its use will give the stamp sufficient movement to print the name on the type-' wheel with hardly a thought of said stopping devices or indicating-mark, the latter being plainly visible to the operator when using the stamp, for the reason that in practice the side of the wheel-case covered by the disk a is before the operator while using the stamp. Instead of fixing said stop-pin in the type-wheel, a slight projection may be formed on the wheel itself for the end of the stop spring 13 to engage with.

The letters of the stamp constituting the name or other matter which is to be printed by the use thereof (shown in Fig. 1) are made, preferably, by constructing a rubber band, on which are formed, in the usual way, the desired letters or figures; but, if preferred, any suitable letters or figures of rubber or other material may be attached directly to or formed upon the said metallic band 12, which constitutes the face of the type-wheel. The aforesaid rubber band 12, havingthe stamp-letters thereon, is passed around the type-wheel, as illustrated in Figs. 1, 2, and 4t, and its ends are secured by a clamp-plate, 8, which is secured to the wheel by suitable screws between which and the side of the wheel the ends of said band are clamped.

By reference to Fig. 4, in which the projecting letters on the band 12 are indicated by dotted lines, it is seen that the said clampplate 8 covers a part of the space on the periphery of the wheel between the first and last letters on the said band, and in adjusting the type-wheel to its proper operative position in the type-wheel case the type-wheel, afterhaving been rotated to print from the matter thereon, is intended to be stopped by the operator when the said clamp-plate comes around opposite the above-referred-to opening in the periphery of the type-wheel case through which the printing-letters are exposed, and therefore when the operator uses the stamp he places the said open portion of the case against the paper, bearing gently thereupon and drawing it over the surface of the latter, thereby causing the type-wheel to rotate by the contact of the milled edge 0 with the paper, the lettering on the type-wheel to be moved over and against the inking-pad and to be rotated in contact with the paper, thereby effecting the printing or stamping. During said operation the operator may or may not, at his pleasure, operate the stop-spring 13, as above described. L By stopping the typewheel, as aforesaid, the printing characters are kept within the case 2 when the stamp is not used, and are protected from dust and dirt.

When the type-wheel is removed from the' case 2, the surface of the inking-pad 4 and the open end of the inking-pad case are clearly exposed, and the inking-pad may have ink easily applied thereto, or it may be replaced with a freshly-inked pad.

A ferrule, 7, is attached to the inking-pad case 5 to receive the end of a handle, 6, when such a handle as is shown in Fig. 1 is used on the stamp; but a very convenient way of using the stamp, under many circumstances, is to attach it to the end of a common lead-pencil, and when so used the said ferrule is made of a greater length than that shown in Fig. 1, and the size of the stamp is adapted to said pencil use.

What I claim as my invention is- In a hand-stamp, the type-wheel case 2, having one side open and an opening through its periphery, combined with the type-Wheel 3, journaled in said case and consisting of the disk at and the circular band 22, secured by one edge thereof to said disk, which constitutes one side of said case, and suitable letters attached to said wheel, substantially as set forth.
